2025-07-23libctf: link: rejig lazy opening to not need weak symbolsusers/nalcock/try-unweaken-libctfNick Alcock1-61/+27
The ctf_link_add_ctf API function has a 'lazy opening' feature whereby, if you pass in the file but not a CTF archive, the archive is opened as late as possible during links. This is valuable mostly in cu-mapped links (a feature not accessible via GNU ld), where it ensures that, rather than eventually needing memory for the original link inputs, the smushed-together cu-mapped intermediate outputs, *and* the final output, we only need enough memory for the smushed- together outputs, the final output, and one input, since the inputs can be closed immediately after they are smushed together. (In GNU ld, the feature is useless because it loads all sections into memory anyway.) The lazy-opening feature uses libctf's ctf_open function, which uses BFD: so it is not available in libctf-nobfd -- except that I thought I had a cunning trick, and used a weak symbol so that if you linked libctf-nobfd into your program and then also linked in bfd, the feature stayed enabled. This is silly -- if your program is licensed such that you can link in BFD, you can just link in libctf.so and not bother with libctf-nobfd.so in the first place. Worse, the weak symbol usage broke MacOS builds, since MacOS's system compiler uses a different means of introducing weak symbols. We could test for and use it, but this is the only place in libctf to use weak symbols at all, and the feature of lazy-opening with libctf-nobfd is so marginal we might as well drop it: it's almost certain there are zero users, certainly fewer users than users of MacOS with the system compiler. While we're at it, simplify things by deleting the never-implemented feature (not exposed in the API) to allow linking together raw buffers of CTF data. If we need it we can bring it back, but all it's doing right now is complicating the code to no end at all. libctf/ * ctf-link.c (ctf_open): Delete weak pragma. (ctf_link_add): Fuse with... (ctf_link_add_ctf): ... this function. Drop BUF, N args and corresponding unimplemented feature warnings. Only check NOBFD to see whether lazy loading is available, not PIC as well.

2025-07-23libctf: don't run tests requiring deduplicating linker unless one is in useNick Alcock5-1/+67
Before now, we were relying on gcc -B to repoint GCC at our freshly-built linker, and assuming we could use this to run tests that do linker dedup. This is, alas, not reliable (building --with-ld=/an/absolute/path bypasses -B searches for the linker), and we would like the libctf tests in particular to not fail if the compiler uses a linker that cannot deduplicate (simply skipping such tests). Add a new testsuite function that tries to link one of the lookup tests' testcases (which is known to produce conflicting types, i.e. a dict with per-translation-unit children) and then does an objdump and greps it for signs of the per-translation-unit children. If there are none, the linker probably just concatenated the sections: i.e., it is not a linker that can deduplicate CTF. libctf/ PR libctf/33162 * testsuite/config/default.exp (objdump): Introduce.

2025-07-23libctf: exclude always-emitted Solaris symbols from the symtypetabRainer Orth1-0/+6
If we're skipping _BEGIN_ and _END_ we should certainly skip all the other ABI-required always-emitted symbols given in ld/emultempl/solaris2*em as well. (This fixes a couple of diagnostics tests, but that's just because the tests are quite sensitive to CTF section sizes, and introducing any symtypetab entries for those tests perturbs those.) Some of these are usually STT_NOTYPE, but not always: if programs already emitted the symbol they might end up with any type, in particular STT_OBJECT, and appear in the symtypetabs.

2025-07-23libctf: get libctf-nobfd.ver from the right place with Solaris ldNick Alcock2-2/+2

2025-07-23libctf: do not use mmap on Solaris 11Rainer Orth2-0/+16
Writable mmaps and read are inconsistent with each other on Solaris 11.4, which breaks archive writing. Simply assert that Solaris 2.11 doesn't have mmap, falling back to read(): the archive format is being bumped shortly, to one with completely different writeout code, so this workaround need not stay for long.

2025-07-23gas: sframe: fix PR gas/33170Indu Bhagat4-4/+71
SFrame generation code assumes that since DW_CFA_restore means restoration of the state of the register to the one at the beginning of the function, there must be a state to restore to (hence the gas_assert (cie_fre)). This assumption needs adjustment. DW_CFA_restore may be present in the very beginning of a (e.g., cold) function, with no initialized state for SFrame functions to restore to. gas/ PR gas/33170 * gas/gen-sframe.c (sframe_xlate_do_restore): Use current FRE if CIE FRE is not yet setup. gas/testsuite/ PR gas/33170 * gas/cfi-sframe/cfi-sframe.exp: New test. * gas/cfi-sframe/cfi-sframe-x86_64-pr33170.d: New test. * gas/cfi-sframe/cfi-sframe-x86_64-pr33170.s: New test.

2025-07-22Fix failing test: i386-avx-reverseShiven Kashyap2-3/+3
Running the standalone test `gdb.reverse` with the target board configuration `unix/-fPIE/-pie` leads to the following failure: ''' FAIL: gdb.reverse/i386-avx-reverse.exp: verify ymm15 before vbroadcastsd ''' This happens because the test expects values stored in `dyn_buf0`, but instead (in the test source) the address of the buffer itself got broadcast to xmm15 (and thus to ymm15). This happened because the pointer to the start of `dyn_buf0` wasn't dereferenced (see 'vpbroadcast_test' in 'i386-avx-reverse.c'): ''' asm volatile ("vbroadcastss %0, %%xmm15": : "m" (dyn_buf0)); ^ ''' and this consequently lead to the test failing for the next instruction (`vbroadcastsd`), which depended on the correct value being broadcast to the register. Also, updated the corresponding expected output (gdb.reverse/i386-avx-reverse.exp) to match. Tested on x86-64 Linux.

2025-07-22RISC-V: Fix the assert fail when linking discarded sections under -pie for gotNelson Chu7-40/+109
Considering the following case, % cat tmp.s .option pic .text .global _start _start: nop .section .discard.s, "ax" la x1, _start % cat tmp.ld OUTPUT_ARCH(riscv) ENTRY(_start) SECTIONS { /DISCARD/ : { *(.discard.*) } . = 0x10000; .text : { *(.text) } . = 0x20000; .got : { *(.got) *(.got.plt)} . = 0x30000; .data : { *(.data) *(.data.*) } } % riscv64-unknown-linux-gnu-as tmp.s -o tmp.o % riscv64-unknown-linux-gnu-ld -pie -Ttmp.ld tmp.o riscv64-unknown-linux-gnu-ld: BFD (GNU Binutils) 2.44.50.20250624 assertion fail binutils-gdb/bfd/elfnn-riscv.c:3638 This happens when pie and the input sections, which refers to the global symbol by got, are all discarded. Since referenced sections are all discarded, we won't go into relocate_section for those sections, the got entry also won't be initialized. Therefore, we will get assert fail when adding the RELATIVE reloc in the finish_dynamic_symbol. After seeing other target codes, there are two root causes as follows, 1. risc-v may call bfd_elf_link_record_dynamic_symbol in the allocate_dynrelocs for not only undefweak symbols. 2. risc-v is missing the code to add RELATIVE to R_RISCV_GOT entries in the relocate_section if a symbol is not dynamic and is not undefined weak under pic and pie. If we call bfd_elf_link_record_dynamic_symbol, then the global symbol will be forced to dynamic, so the h->dynindx will forced to be a number rather than -1, even it should be -1. Once h->dynindx != -1 and pic/pie, it will go into finish_dynamic_symbol and insert RELATIVE/64 relocs for the got entry; For the above case there are two issues, 1. The global symbol _start is forced to be dynamic in the allocate_dynrelocs. when pie and all the referenced section are discarded, it won't go into relocate_section to initialize the got entry, so it will cause assert fail when adding RELATIVE reloc in the finish_dynamic_symbol. The assert fail represents another problem - if we don't initialize the got entry in the relocate_section under pie, which means we don't need to go into the finish_dynamic_symbol and don't need a RELATIVE reloc for the got entry, it should be NONE reloc. 2. Without linking any discarded section, it originally forces every RELATIVE relocs added for every got by the finish_dynamic_symbol. Even The final result looks correct under pie (genearte a RELATIVE reloc for got entry), not sure if it may cause other problems for some special cases, excpet the above one. Therefore, this patch try to fix the above assert fail, and also clarify the behavior of the allocate_dynrelocs which should only call bfd_elf_link_record_dynamic_symbol for undefweak symbols, and add the missing code to generate RELATIVE reloc to R_RISCV_GOT entries in the relocate_section if a symbol is not dynamic and is not undefined weak under pic and pie. Passed the gcc/binutils regressions of riscv-gnu-toolchain at least.

2025-07-21aarch64: Use an enum to refer to indices in the opcode tableRichard Earnshaw7-11646/+13651
The indices into the auto-generated tables for opcodes are relatively unstable. Adding a new opcode can permute the code significantly. But most of this churn is down to changes in the index values. To minimize this use enumerated constants. While the index values change, the enumeration names will need to do so far less often, so most of the changes in the generated code become localized to the addition (occasionally removal) of opcodes. This change also makes the state-change comments unnecessary. The enumeration names contain the same information (and more), so these are simply deleted. The enumeration values are placed in a new header file, aarch64-tbl-2.h, so aarch64-gen gains a new option to build this header and the Makefile rules are adjusted accordingly.
2025-07-21aarch64: use an enumeration for operand indices.Richard Earnshaw3-675/+675
The generated aarch64 operand tables use index values into an array. But if the table of operands is modified by inserting a new operand into the middle of the table, *all* the index values can change, leading to a lot of churn in the generated output. include/opcode/aarch64.h already provides an enumeration for the operands, so make use of that instead of printing out the raw index values.

This field was misnamed in aarch64_opcode_table. It previously didn't matter too much as the name field only appeared in dumps. But it doesn't match the enum in include/opcode/aarch64.h and we will shortly start to rely on that.

PR gprofng/33151 gprofng ignores functions that are compiled as weak symbols. This heavily affects C++ class methods that are always compiled by g++ and clang++ as weak symbols.

PR cli/28887 reports the following problem when using a custom prompt. First, we set up the custom prompt (with ^ marking the position of the blinking cursor on the line above): ... $ gdb -q -ex "set prompt \033[31mgdb$ \033[0m" gdb$ ^ ... Then we type some string, and enter it into the command history: ... gdb$ some long command ❌️ Undefined command: "some". Try "help". gdb$ ^ ... We use C-p to fetch the previous command: ... gdb$ some long command ^ ... Sofar, so good. Finally, we use C-a which should move the cursor to just after the prompt, but instead we get: ... gdb$ some long command ^ ... This is fixed by using \001 and \002: ... (gdb) set prompt \001\033[31m\002gdb$ \001\033[0m\002 ... aka as RL_PROMPT_START_IGNORE and RL_PROMPT_END_IGNORE [1]. Add an example to the documentation showing the use of these markers. The added example is the equivalent of the "\[\e[0;34m\](gdb)\[\e[0m\]" example documented at gdb.prompt.substitute_string that can be used with "set extended-prompt". While working on this, I noticed that "show prompt" doesn't show back the original string, using '\e' instead of '\033': ... gdb$ show prompt Gdb's prompt is "\001\e[31m\002gdb$ \001\e[0m\002". ... and that the shown string can't be used as an argument to "set prompt": ... gdb$ set prompt \001\e[31m\002gdb$ \001\e[0m\002 e[31mgdb$ e[0m ...

(gdb) bt^M Required frame unwinder may have been disabled, \ see 'maint info frame-unwinders'^M (gdb) FAIL: $exp: verify unwind fail without CFI ...

(gdb) bt^M Python Exception <class 'gdb.error'>: \ Required frame unwinder may have been disabled, \ see 'maint info frame-unwinders'^M (gdb) PASS: $exp: verify unwind fail without CFI ... but if I change the "bt" into "bt -no-filters" I get the same FAIL and corresponding output. So there are two scenarios here. In the first: - the bt command is called - frame #0 is printed - trying to get the next frame fails and an error is thrown, aborting the backtrace - the error is caught and printed In the second: - the bt command is called - the frame filter is applied - doing so triggers the same error, which is caught and printed by gdbpy_apply_frame_filter, returning EXT_LANG_BT_NO_FILTERS - frame #0 is printed - getting the next frame fails, and the backtrace stops It seems worthwhile to exercise both scenarios if possible, so add a "bt -no-filters" test. Fix the FAIL by updating the regexp to allow both scenarios. Tested on aarch64-linux. Reviewed-By: Keith Seitz <keiths@redhat.com>

2025-07-19RELOC_AGAINST_DISCARDED_SECTION zero size reloc sectionsAlan Modra7-52/+25
For some reason the initial implementation (commit 0672748ac053) of this macro didn't allow discarding of all relocs in a section, perhaps because doing so would require a testsuite change. This patch allows zero size relocation sections to result, and adjusts the testsuite. i386, x86_64, ppc and ppc64 code that avoids a memmove is also changed to allow zero size reloc sections, and arc fixed to actually adjust the reloc section header.
2025-07-18[gdb/testsuite] Fix gdb.arch/amd64-disp-step-self-call.exp on freebsdTom de Vries4-44/+38
On x86_64-freebsd, with test-case gdb.arch/amd64-disp-step-self-call.exp, I run into: ... (gdb) continue Continuing. Program received signal SIGBUS, Bus error. Object-specific hardware error. 0x000000080051492c in alarm () from /lib/libc.so.7 (gdb) FAIL: $exp: continue to breakpoint: test_call ... The behaviour is not specific to gdb, it can be reproduced by running the test-case executable: ... $ ./outputs/gdb.arch/amd64-disp-step-self-call/amd64-disp-step-self-call Bus error (core dumped) $ ... The bus error happens when executing this instruction in alarm: ... 0000000000093910 <alarm>: ... 9392c: 0f 29 45 d0 movaps %xmm0, -0x30(%rbp) ... because $rbp is not 16-byte aligned. This can be fixed by adding the missing frame setup instructions at the start of main in amd64-disp-step-self-call.S: ... main: + pushq %rbp + movq %rsp, %rbp ... Instead, fix this by moving main from the assembly file to the c file, which has the same effect. Also remove the done label, which looks like a copy-past left-over. Instead, add an unreachable function and use it where appropriate. Do the same for i386 case (which makes the source files identical for the amd64 and i386 case, but I decided to leave it like that). Tested on x86_64-freebsd and x86_64-linux.
2025-07-18gdb/testsuite: mark the start of each gdb.in.* log fileAndrew Burgess1-0/+4
Emit a line in the gdb.log file each time a new gdb.in.NUM command log is started. The gdb.log line includes the full filename for the new gdb.in.NUM file. This change will make it trivial to go from a FAIL in the gdb.log file to the gdb.in.NUM file that (should) reproduce the failure. When I encounter a failing test one of my first steps is usually to identify the gdb.in.NUM file and try re-running it to see if that reproduces the failure. Some tests create many very similar gdb.in.NUM files, so finding the exact one can sometimes be difficult. With this patch that task is now trivial. There should be no change in what is tested after this commit. Approved-By: Simon Marchi <simon.marchi@efficios.com>
